Reports fields of type <code>java.lang.ThreadLocal</code> that are not declared <code>static final</code>.
|
|
<p>
|
|
In the most common case, a <code>java.lang.ThreadLocal</code> instance associates state with a thread.
|
|
A non-static non-final <code>java.lang.ThreadLocal</code> field associates state with an instance-thread combination.
|
|
This is usually unnecessary and quite often is a bug that can cause memory leaks and incorrect behavior.
|

</p>
|
|
<p>
|
|
A quick-fix is suggested to make the field <code>static final</code>.
|
|
<p>
|
|
<p><b>Example:</b></p>
|
|
<pre><code>
|
|
private ThreadLocal tl = ThreadLocal.withInitial(() -> Boolean.TRUE);
|
|
</code></pre>
